Cloud machines have a way better guarantee about such errors though. You will eventually see some errors at scale, but that error rate can be reliably quantified and handled accordingly.

Consumer machines are comparably wild. Remember that this issue was mainly spotted from Unreal error messages. Some do too much overclocking without enough testing, which will eventually harm the hardware anyway. Some happen to live in places where single-error upsets are more frequent (for example, high altitude or more radioactive bedrock). Some have an insufficient power supply that causes erratic behaviors only on heavy load. All those conditions can be handled in principle, but are much harder to do so in practice. So giving up is much more reasonable in this context.
